Research on Power Information Network Slicing Security Deployment Algorithm
Currently,deployment method for network slicing is susceptible to the influence of the incommensurability of network security evaluation indexes,resulting in a high average bit loss rate of network slicing after deployment.Aiming at this problem,a security deployment algorithm for power information network slicing based on security performance perception is designed.Based on the underlying physical network deployment model,the constraints of network slicing resource allocation are designed.To smooth out the incommensurability of the evaluation indexes,the security level decision matrix is weighted.The network security level is ranked.Based on the principle of security performance perception,the security deployment model is constructed with the objectives of minimizing the network performance impact factor and minimizing the network slicing deployment cost,and the discrete particle swarm algorithm is used to solve the model to obtain the optimal deployment scheme.The experimental results show that after utilizing the algorithm,the average bit loss rate of network slicing is low,and the resource utilization rate after network attack is always kept above 60％.The algorithm can effectively ensure network security.
